To a/ZZ whom it may concern.'

Be it known that I, HERMANN KLAHRE, a

- resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Gas and Air Mixers, ofwhich the following is hereby declared to be a full, clear, and exactdescription, sufficient to enable others skilled in the art to whichsuch invention relates to make and use the same.

The invention relates to gas-holders of the usual type comprising anopen inverted drum submerged within an inclosing Water-tank; and suchinvention consists of certain improvements in structure whereby theholder receives air and gas in separate chambers of the drum anddischarges the same suitably mixed into a carburetor of anyapprovedpattern, wherein the mixed air and gas are enriched withgasoline or other vapor preparaq tory to burning for illumination.

The invention designs to control the admission of air and gas to theholder automatically under conditions dependent upon the consumption ofthe carbureted gas and air and the consequent `falling of the inverted.drum within its Awater-tank.

The nature of the improvements will fully appear from theY descriptionfollowing, and be thereafter more distinctly pointed out in the claimsat the conclusion thereof.

In the 'accompanying' drawings, forming part of this specification, likeletters of reference denote like parts of structure throughout.

Figure l is a View of the improved holder in longitudinal section online l 1 of Fig. 3. Fig. 2 is a like view on line? 2 of Fig. l. Fig. 3is a view in cross-seetion on line 3 3 of Fig. l. inlet valve.

Mounted within the submerging water-tank A,-of ordinary construction, isthe open inverted drum B, having its lower vend to dip within the waterin tank A for the purpose of effecting a seal, as well understood. The

'space within the drum B above the water Fig. 4 is a detail section viewof the acid upon Zinc or iron filings or the like.

der being of comparatively small diameter and extending downwardly1 forabout the depth of the drum. An inlet-pipe a extends through the side ofthe tank A and opens into the annular space or chamber of the drum Bexternal to the cylinder l). The pipe` a at its outer end terminates ina goose-neck to suitably receive and seat the ball-valve c, and at itsinner end said pipe a is furnished with a proper cage to receive theball-valve d. The Oneway valves c CZ open inwardly to permit the freeadmission of the air to the drum B during the upward movement of suchdrum, Vhen, however, the drum descends, the valves c d close againsttheir seats and check the exit of air through the pipe a. Ex-

cept for greater certainty inA preventing the reflux of air through thepipe a, but one of such valves c d need be employed, and it is obvious,also, that any other form of valve moving' lightly to and from its seatmay be substituted in place of the ball-valvesc d.

The gas-induct pipe passes through the wall of the tank A and openswithin the inner cylinder b above the water seal. communicatesexternally with any suitable source of gas-supplysuch, for example, asproduces hydrogen gas by action of sulphuric At its inner terminal saidpipe e is furnished with a on e-way yalvef, which, as in the form shown,may conveniently be of the piston type, having a stem ',q, which extendsupwardly into the trip or shifting case 7i, fastened to the underside ofthe top of the drum B. The valve f closes againstthe seat, as at 1'.,secured to the end of the pipe e, and is preferably furnished withspring-lingers le, which bear against the stem Q of the valve and guidethe latter firmly to its seat. The spring-fingers k. serve also toretain the valve f in closed position during the descent of the drum Buntil the head Z of the valve-stem g is struck by the top of the drum B.During the upward movement of the drum the head l of the valve-stem glinally engages with the inturned lugs of the trip @which thereby liftthe valve f against its seat l and check the further admission of gas tothe holder.

The eductionpipes m n, leading, respectively, from the air and gaschambers of the The pipe e IOC holder, are preferably furnished withgooseneck terminals having ball-valves o p therein, and said pipesdischarge into a common delivery-pipe q, which extends thence to thecarburetor of any suitable pattern.

Instead of the ball-valves o p the eductionpipes m n may be furnishedwith any other type of light-moving one-Way valve, or such valves may beentirely dispensed with, and a single one-Way valve beemployed, located,as shown in dotted lines, in the common delivery-pipe q. Since the innerends of the pipes m nare above the line of Water seal of the gas-holder,the air and gas Within the chambers of the holder on release of pressureat the carburetor or beyond lightly lift the valves o p and becomefreely mixed in the delivery-pipe q, passing thence to the carburetor tobe enriched.

Instead of attaching the pipes m 'n to each other by a T-joint Withinthe tank A, it is manifest that these may be so joined beyond the tankor be connected With a common delivery-.pipe discharging into thecarburetor.

According to the invention detailed gas and air in proper volumes Willbe admitted into the holder until the same is filled, When the furthersupply will be checked automatically by the closing of the gas-valve fagainst its `valves c d in the induct-pipe a and by the valve f in theinduet-pipe e, respectively. The one-way valves o p, or the single valvein delivery-pipe q, as the c'ase may be, will which, consequently, isnot limited to such details.

Having thus described the invention, what I claim as new, and desire tosecure by Iletters Patent, is

l. The combination,with the holder having separate air and gas chambers,and with the induct and educt pipes severally leading to and from eachof said chambers, of the oneway inlet-valves singly for saidinduct-pipes and the one-Way outlet-valves (or valve) singly for saideduct-pipe's, respectively, the inlet`valve for the' gas-induct pipebeing controlled automatically by movement of the inverted drum of theholder, while the outlet# pipes are free to discharge on release ofpressure beyond their valves (or valve) irrespective of the position orshift of such holder, substantially as described. v

2. The combination, with the inverted drum of the holder having separateair and gas chambers, of the induct-pipes opening severally into saidchambers, the one-way inletvalves for said pipes,(the gas-inlet valvebeing furnished With an extended stem which coacts Withl a trip fromsaid ldrum,) and the eductpipes leading severally from said chambers,such pipes having inner goose-neck terminals with ball-valves therein,whereby said outlet-pipes are free to discharge on release of pressurebeyond the valves irrespective of the position or shift of said holder,substantially as described.

3. The combination, with the gas-holder having the usual inverted drum,of an induct- -pipe, a one-Way inlet-valve mounted thereon and furnishedWith an extended stem, and a trip projectinginwardly Within said drum toengage such stem and shift the valve, substantially as described.

4. In gas-holders, the con1bination,with the inverted drum and' theinlet-pipe therefor having a valve-seat t' and spring-lingers kextending therefrom, of the valve j', bearing against said seat, thestem j, projecting from said valve Within the clasp of thespring-iingers and having a cross-head terminal l, and the trip h,carried by the drum and having inturned lugs to coact With saidcross-head, substantially as described.
